Description

Technical Field

[0001] The utility model relates to an earthwork backfilling and compacting device, belonging to the technical field of earthwork construction. Background Art

[0002] Backfilling is the earth filling construction of construction projects, mainly including foundation filling, foundation pit (trench) or pipe trench backfilling, indoor floor backfilling, outdoor site backfilling and leveling, etc. After backfilling, the earth needs to be compacted. The compaction methods generally include rolling, tamping, vibration compaction or compaction using earth moving tools. Hydraulic compactors are usually used for compaction when backfilling.

[0003] When the existing hydraulic rammer is in use, its working principle is that the hydraulic cylinder lifts the hammer to a set height and then releases it, and the hammer falls freely. After the hammer falls, it hits the assembly of the hammer and the rammer plate through the hammer pad, driving the rammer plate to compact the ground. In this process, since the rammer plate hits and compacts the ground, dust on the ground will fly everywhere, generating dust. The existing hydraulic rammer is not equipped with a dust suppression structure, and cannot suppress the dust, polluting the construction environment. Now there is an urgent need for an earth backfilling and compacting device to solve the above-mentioned problems. Utility Model Content

[0006] The spray dust suppression mechanism includes a first water pump, a water tank, a supporting base plate, a second water pump, a water hose, a fixed frame, a water spray pipe, an end socket and an atomizing nozzle. The supporting base plate is arranged on the upper side of the machine body, a water tank is arranged on the upper side of the supporting base plate, a first water pump is arranged on the upper side of the water tank, a second water pump is arranged on the right side of the water tank, a fixed frame is welded and fixed on the lower side of the annular side of the machine body, a water spray pipe is arranged on the outside of the fixed frame, an atomizing nozzle is arranged on the outside of the annular side of the water spray pipe, end sockets are arranged at the connection between the two ends of the water spray pipe and the fixed frame, and a water hose is arranged at the connection between the second water pump and the water spray pipe.
